Hi,
I have a working installation of Playsms. I am trying to send out test SMS using the Nexmo gateway but I cannot through the Playsms web portal. I have the Nexmo URL, API key and API secret configured correctly. I get the error below when i check the logs;

When I test sending with Nexmo on the server’s cmd using the ‘Curl command’, I am able to send out the sms.

Kindly assist in explaining what I might be doing wrong on the Playsms web GUI.
